Abstract

The invention discloses an antibacterial peptide-containing pesticide composition. The pesticide composition contains an active ingredient A and an active ingredient B. The active ingredient A is antibacterial peptide and the active ingredient B is selected from cyazofamid, cymoxanil and dimethomorph. A weight ratio of the active ingredient A to the active ingredient B is 1: 80 to 80: 1. The antibacterial peptide-containing pesticide composition has high activity of treating a plurality of diseases of crops and has characteristics of crop root development stimulation, crop growth promotion, yield increasing and crop quality improvement.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a pesticide composition containing antimicrobial peptides on crop diseases. Background technique [0002] Antimicrobial peptides are a class of small molecule polypeptides with antibacterial activity, which widely exist in living organisms. They have the characteristics of small molecular weight, stable biological activity, unique mechanism of action, and are not easy to produce drug resistance. Killing effect. It has wide antibacterial spectrum, good stress resistance, easy fermentation, storage and transportation, and is an excellent strain with good application and development prospects. The structural formula of the antimicrobial peptide is [0003] [0004] Cyazofamid, cymoxanil or dimethomorph are common fungicides widely used in crop diseases. [0005] In addition, metalaxyl and salt, valfafencarb, dicyanoanthraquinone, cyprodinil, captan, aluminu...
